Fire Rainbow Over Chilean Mountain in Late Spring

Brilliant spectral bands stretch horizontally across pale blue sky, cutting through thin, wispy cirrus clouds above a rugged Andean peak. The light rainbow, or circumhorizontal arc, glows with intense white and soft pastel hues, contrasting against the deep azure background. Below, the mountain face displays rough, gray rock textures and patches of dry, late-spring grasses clinging to the slope. A diagonal line of cloud formations creates visual tension, slanting sharply from the upper left toward the lower right. Wind ripples the surface of a lake in the foreground, distorting the reflection of the arc into shimmering, broken ribbons of color. The water's surface moves constantly, showing the light while the air above remains still and clear. The edge of a dark rock in the bottom corner anchors the diagonal composition.
